Okay this kinda hard that I can’t even answer it
Which sentence? i’ll definitely help:)
The correct option is: <em>the reader could set his or her own pace and reread parts for clarity.</em>
When we read a text, we are able to do it in <em>our own pace</em>, <em>managing our time</em>, and <em>reading again</em> the parts we could not understand the first time.
On the other hand, <em>listening to audios</em> (or watching videos) can easily <em>affect our emotional perception</em> about a particular theme.
A gerund is a verb changed into a noun by adding 'ing' to the end of the word.
So your answer is B. Jogging
Hope this helps. :)
